,l This `inyention relates'to d, an improvement in .battfe'ry'fl 'lnsand more' especially to additionally supportingf the `battery of ,the loom and 'also for supporting the bobbin ,supporting means assoelated 'with the hopper of' the battery loom, espe- 'cially whentheprojection on the hopper for sup- "porting` the hobbinsupport isbroken `as often `happens. Also, there is.a tendency at the present date totrytospeed upjtheiimber of picks per minute in looms.A As longfas a'loorn is runningaround 150 pickspermirite, the .vibrationis not so great, buty whenthis loom fis operated at from 170 or ,more `picks per minute, therefis excessive vibration in 'the loom" and by `I,I1y improved supporting means the amount' of vibration and damage to ,theloomis greatly overcome. i

Also, it'often happens `that the peripheral projection onthe lower portion .of the hopperstand offa loom which accommodates a `pivot bolt for the bobbin" support which supports a bobbin l,about to be transferred is broken away and thus thehopper fstand isrendered useless and a new hopper `stand has .to ,be installed, fbut by `my irnproved means, an` additional lsupport for the' pivot bolt of the ,bobbin lsupport can be provided and the old"l`1opper"wliih` has been broken can be used without ,thaneeessity of discarding the same. It is therefore an object of this invention to provide means secured to a rigid Vportion of the loom and also secured to the hopper of the battery in a battery lo'orn for additionallylsupporting the battery hopper, and said supporting means ,can also, ifdesired, have a supporting means extendingtherefrorn to `a point `,where thelbobbin hsupportcanbe supported especially when the broken away. r Some of Vthe objects of the invention having been stated, other objects will appear as the description proceeds when taken in connection with the accompanying drawings, in which Figure 1 is a vertical sectional view, mostly in elevation, and looking at the back side of a battery for a loom;

Figure 2 is a sectional plan View taken along the line 2 2 in Figure 1;

Figure 3 is a view similar to Figure 1 but showing a modied form of the invention;

Figure 4 is a vertical sectional view taken substantially along the line 4 4 in Figure 1.

Referring more specifically to the drawings, the numeral in indicates a portion of a loom frame having a plate or breast beam H and also being provided with a lay I3 having a race plate bobbin supporting portion of thelhopper has .been

s claims. lol; 13e- 249) Id anda suitable shuttle box on each endthereof, a portion of which is" indicated at l5, and into which shuttles I6 may be projected in-which posi,- tionthey are disposed during a transfer operation. This loom has a hopper standA il? secured thereto by one or more screws 2i. This hopper stand has a transfer-stud@ fixed therein by any suitable means such` as afscrew 23, and supports a transfer aljrn,` not shown.' Th'e`,hoppe l'-stand has centrally mounted therein a bobbin disk stud 25 which is coni-ined in position by a nut 25. O'n the bobbin disk studffisfmounted for rotation a bobbin disk 21' Ahaving 'a plurality of radially disposed pockets 3D7d'ispo'se'd around its periphery in which the butt's lof bobbinsfl are adaptedto be disposed. "The hopper stand has extending substantially allthway around its periphery a ange 33j-whichprevents the bobbins from fall'- ing 'outof the pockets in the bobbin disk except `when ,they have reached-transfer position at the lowerrnost part off the hopper stand, where the projectionor rib 33 isnot present. Extendingfrom'the periphery of the `hopper stand is a projection ALBlIl/hich has a transverse bore therethroughi'ir which abobbinsupport bolt 36 lis mounted. "This'bobbin support is substanf# tiallyof the structre'shown in `Patent Number 12291420 o"fMa'.rch"18,` 1919,3"a'nd comprises va poi"- tionf`3`l forsupporti'ng the'lowermost bobbinyabout to be transferred and alsoha's a'tail portionY 38 Vwhich isA trough "shaped'andhas portions appearing on both sidesfof the-hopper `sta'nd'and a transn verse" bore-extends through the portion 38and is penetrated by" the *pivot bolt 3,6 for pivotally .Supportinelthelbehbiasuevert l The` `bolcgbi 's port has integral therewith' an arm 4,0111 Whitv -i'..m'i1r.1ted"a bolt @M 'Wlflifih `slilatry penetrates la projection ,4.2, exten... ne from therear surface of th* hopper standand a compression spring 44 is disposed between the projection 42 and the headed end of the ybolt 4i to apply proper tension to the linger portion 31 which supports the bobbin about to be trans-a ferred into the shuttle. The parts thus; far described are conventional and it is with a structure of this sort that my invention is adapted to be associated.

During operation of a loom, it very often happens that the projection 35 is broken away as shown in Figure 1 and therefore no means are provided for supporting the bobbin support.

My invention comprises means for supporting this bobbin support pivot bolt so that it is not necessary to install a new hopper stand. My invention also supports the hopper stand from another portion of the loom to thereby reduce vibration to a minimum when the loom is operated, especially at a high rate of speed. Y

A loom has an upright and frame member or post 50 on each side thereof which are joined together at their upper ends by an arched portion, not shown. I provide a member, such as a strap iron member 5|, and secure one end thereof by means of a bolt 52 to one of the webs of the channelled uprights 50 and another bolt 53 penetrates one leg of an angle bracket 54 as well as the portion 5| to secure the angle bracket to the portion 5| and the other leg of the angle bracket 54 is penetrated by. a bolt 56, which penetrates a washer 5l and also penetrates a channel member 50 for rigidly supporting one end of the member 5|. The angle member 54 has a downwardly extending leg 59 which is adapted to rest against the post 50 to additionally brace the member 5|.

The member 5| has an elongated slot 60 therein which is penetrated bythe bolts 52 and 53 to thereby adjust the position of the member 5| with relation to the post50. The member 5| is bent laterally and downwardly as at 52 and has a horizontally disposed portion 63 having a hole in its right-hand end in Figures 1 and 2 which is penetrated by the bobbin disk stud, and the bobbin disk stud bolt 26 confines that end of member 63 in position. v

The form of the invention shown in Figure 3 and which has just been described can be us-ed for bracing the hopper stand of a. loom where the projection for supporting the bobbin support has not been broken away. Where this bobbin supporting projection 35 has been broken away, then I may secure by means of bolts it the upper end of a member 1| which projects downwardly and then laterally and has an enlarged lower end i3 which is bored to receive the bobbin support bolt 35 to thus support the bobbin support where the supporting projection 35 has been bro-ken away rom the hopper stand.-

If desired, this member 'il could be employed for additionally supporting the bobbin support bolt 36 even in a hopper stand which did not have the projection 35 broken away from the same and would thus prevent breakage of the projection 35 away from the loom.

It is thus seen that I have provided additional supporting means for the battery hopper stand of a loom and also means associated therewith, if desired, for supporting the bobbin support associated with the battery of the loom.

In the drawings and specication there has been set forth a preferred embodiment of the invention, and although specic terms are employed, they are used in a generic and descriptive sense only, and not for purposes of limitation, the scope of the invention being defined in the claims.

I claim:

1. In a bobbin changing loom having a frame and a bobbin support and a hopper stand, a supporting device for the bobbin support comprising a bracing member secured at one end to a portion of the loom frame and secured at its other end to a portion of the hopper stand of the loom, said bracing member being provided with a downwardly projecting member having a hole through its lower end adapted to be penetrated by a bolt on which the bobbin support is mounted.

2. A loom having a frame, a breast beam, and an uprising member integral with the frame, a battery hopper stand mounted on the breast beam, a bobbin disk stud mounted in said battery hopper stand, a bobbin support which is normally oscillatably mounted in the battery hopper stand, a brace bar secured to the uprising member of the loom at one end and secured on one end of the bobbin disk stud at its other end, an L-shaped member extending downwardly from the brace bar, a bolt extending transversely in the lower end of said L-shaped member and having the bobbin support oscillatably mounted thereon.

3. In a loom having a battery comprising a hopper stand and a bobbin disk and a bobbin disk stud and a bobbin support member for supporting a bobbin about to be transferred, and a bolt on which the bobbin support is mounted for pivotal movement, said loom also having an uprising frame member, a brace member, means for securing one end of the brace member'to the uprising frame member of the loom, and the other end of the brace member having a hole therethrough adapted to be penetrated by the bobbin disk stud for supporting the hopper stand from the uprising frame member of the loom, the brace member having a downwardly extending arm portion provided with a hole in its lower end adapted to be penetrated by the bolt which supports the bobbin support for thus also supporting the bobbin support of the battery.
